I am trying to abstract code to make an image by making a macro. Could someone please explain why this does not work?

\newcommand[1]{\custpic}{\begin{figure}[H]\begin{center}\includegraphics[width=0.5\textwidth]{#1}\end{center}\caption{}\end{figure}} % url

\custpic{4b.png}

What is confusing me is that this does work as expected.

\newcommand[1]{\custpic}{\begin{figure}[H]\begin{center}\includegraphics[width=0.5\textwidth]{4b.png}\end{center}\caption{}\end{figure}}

\custpic

Thank you very much

Try with \newcommand{\custpic}[1]{...} instead of \newcommand[1]{\custpic}{...}... – Paul Gaborit Mar 6 at 0:26
Yes, in the definition, the optional argument, which indicates the number of arguments of your new command, comes after the name of your command. – Jubobs Mar 6 at 0:29
It does indeed fix it. Thank you very much PaulGaborit and Jubobs. – superbriggs Mar 6 at 0:30

\centering is usually better than \begin{center}... for figures: tex.stackexchange.com/questions/23650/… – Ethan Bolker Mar 6 at 1:01
